They should really be looking at the whole Bristol Channel/estuary.

Massive environmental impact and enormous cost. A better alternative
surely are marine turbines. Less impact, less cost, and installable
over a large part of the estuary, as you suggest. But still no leccy
at slack water, the weakness of all tidal systems.

An even better alternative is a f****** great nuke.
